Mike,
As further clarification of my setup, I am simply trying to use HRD on the Control RRC to operate a K3 on the Radio RRC. I have the Radio Settings on Transparent for both the Control RRC and the Radio RRC. I have the Serial settings on Mode 4 for Radio RRC and Control RRC.
Is this correct?
Also, as a separate test, I attached a cable to COM2 on the Radio RRC and ran the cable to a COM port on my PC. I used two different terminal programs to see if I saw any output from COM2. I am seeing nothing from the port.
Is this normal or do I have a defective unit?
Thanks for a reply,
Bob K5WA
